automation - Gluing (Imposition) PDF documents

Question

I have several A4 PDF documents which I would like (two into one) "glue" together into A3 format PDF document. So I will get from 2PDFs A4 a single one sided PDF A3. I have found the excellent utility PDFToolkit and some others but none of them can be used to "glue" side by side two documents.

Answer 1

I just came across a nice tool on superuser.com called PDFjam that can do all of the above in a single command:

pdfjam --nup 2x1 file1.pdf file2.pdf --outfile DONESKI.pdf

It has other standard features like page size plus a nice syntax for more sophisticated collations of pages (the tricky page re-ordering necessary for true booklet-style page imposition).

It's built on top of TeX which is, whatever it is. Installing is a breeze on Ubuntu: you can just apt-get install pdfjam. On Mac OS, I recommend getting BasicTeX (google "mactex basictex"; SO thinks I'm a spammer and won't let me post the link).

This is a lot easier and more maintanable than installing both pdftk and Multivalent (on both Mac OS for dev and Ubuntu for deploy), which wasn't going so well for me anyway...!
